I’m with you there. I’m 6’3 235-240 and I have to wear xxl in kuiu. Especially if it’s being layered. It’s odd: their sizing model...I prefer my First lite over any brand I’ve owned, I a large guy (6’4 -290ish) and they work well for me. Most other brands seem to be short in the arms or I can’t lift my arms up without them looking like a belly shirt.
